New laser nose will sniff out first signs of cancer
April 05, 2004
SCIENTISTS in Scotland have developed a "breathalyser" that can detect early signs of lung cancer.
The hyper-sensitive machine, dubbed a "laser nose", detects tiny traces of ethane in the breath, using technology originally designed for oil prospecting.
Patients use the device by breathing down a tube into a bag, where a tiny laser beam detects ethane, produced when lung cancer breaks down cells in the body.
